Circuit Uncle brought to you a water or liquid level sensor for online purchase in India, which you can use to make highly accurate water level indicator circuits. This water level sensor is an easy-to-use, cost-effective solution to identifying the presence of water or other conducting liquids. When the Water level sensor parallel conducting strips is immersed in water or other conducting liquids a voltage is produced which is proportional to the level of the water. The voltage is directly read to analog input pins of Arduino UNO or Arduino Nano.

Water Liquid Level Sensor Pin Connections with Arduino and other microcontrollers

  • VCC ↔ 2.0V ~ 5.0V
  • GND ↔ power supply ground
  • AOUT ↔ MCU’s  I/O (analog output)

This sensor can be used with a microcontroller or Arduino to actuate a pump, an indicator, an alarm, or another device. Can use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating, pumps, ponds, basement alarms, boats, air condition drain pans, pressure washers, carpet cleaning machine, reef aquarium, fluid control, ice machines, coffee pots, marine, automotive, automobiles, tropical fish tanks, evaporator coils, etc.

The best thing about this water level sensor is this is compact and lightweight. Though you can’t measure a large water depth i.e., 4 cm maximum, but the reading will be linear, i.e., the output to analog signal is directly proportional to the water level. Water level sensor in India and worldwide is popularly used for DIY student projects. As the output voltage is linear, it finds some applications in the industry too!

  1. Eldo Jhon

    This sensor’s output is very linear. But very small-sized, so be aware of the size before buying it.
